Additional Notes

  • The BMW X4 G02/F98 transfer case fluid capacity is 0.7 liter across all listed configurations, covering both the xDrive M40i and xDrive30i variants.
  • The 0.7 liter figure represents a service fill capacity, meaning the amount of fluid the transfer case holds during a standard fluid change rather than a full overhaul procedure.
  • All four rows carry a normal use condition tied to the 0.7 liter capacity, indicating the specification applies to standard operating conditions rather than a severe-duty service interval.
  • The xDrive M40i and xDrive30i share an identical 0.7 liter transfer case capacity, showing no variation between the performance-oriented M40i and the standard xDrive30i in terms of transfer case fluid volume.
  • Both the 2018-2019 and 2019-onward entries for each variant list the same 0.7 liter capacity, indicating no change in transfer case fluid volume between the earlier and later production runs of either model.
